According to your application the site is to serve a 4 bedroom home with a design wastewater flow of 480 gallons per day. The evaluation was done in accordance with the laws and rules governing wastewater systems in North Carolina General Statute 130A-333 including related statutes and Title 15A, Subchapter 18A,of the North Carolina Administrative Code,Rule.1900 and related rules. Based on the criteria set out in Title 15A,Subchapter 18A,of the North Carolina Administrative Code, Rule.1940 through .1948,the evaluation indicated that the site is UNSUITABLE for a sanitary system of sewage treatment and disposal. Therefore,we must deny your request for an Improvement Permit. A copy of the site evaluation is enclosed. The site is unsuitable based on the following: X Unsuitable soil topography and/or landscape position(Rule.1940) Unsuitable soil characteristics(structure or clay mineralogy)(Rule.1941) X Unsuitable soil wetness condition(Rule.1942) Unsuitable soil depth(Rule .1943) Presence of restrictive horizon (Rule .1944) X Insufficient space for septic system and repair area(Rule.1945) Unsuitable for meeting required setbacks(Rule.1950) Other(Rule.1946) These severe soil or site limitations could cause premature system failure,leading to the discharge of untreated sewage on the ground surface,into surface waters,directly to ground water or inside your structure. The site evaluation included consideration of possible site modifications,as well as use of modified, innovative,or alternative systems. However,the Health Department has determined that none of the above options will overcome the severe conditions on this site. A possible option might be a system designed to dispose of sewage to another area of suitable soil or off-site to additional property. catawbacountync.gov Environmental Health Catawba County Government Center 25 Government Drive I PO Box 389 I Newton NC 28658 1828.465.8270 MAKING.

(b) Basic Field Evaluation Procedures: (I) A soil wetness condition shall be determined by the indication of colors of chroma 2 or less(Monsell Color Charts)at>2%of soil volume in mottles or matrix of a horizon or horizon subdivision. However,colors of chroma 2 or less which arc relic from minerals of the parent material shall not be considered indicative of'a soil wetness condition. (2) A Soil wetness condition shall also be determined by the periodic direct observation or indication of saturated soils or a perchcd water table,or lateral water movement flowing into a bore hole,monitoring well,or open excavation above a less permeable horizon or horizon subdivision,that may occur without the presence of colors of chroma 2 or less. A soil wetness condition caused by saturated soils or a perched water table shall be confirmed to extend for at least three consecutive days.The shallowest depth to soil wetness condition determined by Subparagraph(b)(I)or(b)(2)of this Rule shall take precedence. (c) Site Suitability as to Soil Wetness: Initial suitability of the site as to soil wetness shall be determined based upon the findings of the Basic Field Evaluation Procedures made pursuant to Paragraph (b)of this Rule. Sites where soil wetness conditions are greater than 48 inches below the naturally occurring soil surface shall be considered SUITABLE with respect to soil wetness.Sites where soil wetness conditions arc between 36and 48 inches below the naturally occurring soil surface shall be considered PROVISIONALLY SUITABLE with respect to soil wetness. Sites where soil wetness conditions arc less than 36 inches below the naturally occurring soil surface shall be considered UNSUITABLE with respect to soil wetness, Sites where a soil wetness condition is determined based upon the observation or indication of lateral water movement within 48 inches of the naturally occurring soil surface shall be considered UNSUITABLE, except when such water can be intercepted in accordance with I5A NCAC 18A.1956(4). (d) Alternative Procedures for Soil Wetness Determination: The Owner or the Owner's Legal Representative(Applicant) shall have the opportunity to submit documentation that the soil wetness condition and resultant site classification be alternately determined and reclassified by direct monitoring, computer modeling, or a combination of monitoring and modeling,in accordance with a Direct Monitoring Procedure,Monitoring and Modeling Procedure,or Modeling Procedure made pursuant to Paragraphs(c).(t),or(g)of this Rule. This determination shall take precedence over the determination made pursuant to the Basic Field Evaluation Procedures[Paragraph(b)of this Rule],when the conditions of Paragraphs(c). (f), or(g)of this Rule arc met_ Determination by one of'these Monitoring or Modeling procedures shall also be required when: (I) the Owner proposes to use a wastewater system requiring a deeper depth to a soil wetness condition than the depth determined by the Basic Field Evaluation Procedures pursuant to Paragraph(b)of this Rule;or (2) the Owner proposes to use sites with Group III or IV soil within 36 inches of the surface and where drainage modifications arc proposed to be made, including the installation of subsurface drain tile,open drainage ditches,or surface landscape modifications,or on such sites when fill is proposed to be used in conjunction with existing or proposed drainage modifications. Final determination of soil wetness condition for these sites shall be made pursuant to the Modeling Procedure in Paragraph(g)of this Rule (c) Direct Monitoring Procedure. Soil wetness conditions may be determined by direct observation of the water surface in wells during periods of typically high water elevations utilizing the following monitoring procedures and interpretation method. (I) The applicant shall notify the local health department of the intent to monitor water surface elevations by submitting a proposal that includes a site plan, well and soil profile at each monitoring location,and a monitoring plan no later than 31)days prior to the monitoring period. An applicant other than the property owner shall have written authorization front the owner to be the owner's legal representative.Soil wetness and rainfall monitoring shall be conducted under the responsible charge of a third-party consultant or by the property owner or the owner's agent. A third party consultant is qualified when licensed or registered in accordance with G.S. 89C(Engineers),G.S.89E(Geologists),G.S.89F(Soil Scientists).or G.S.90A Article 4 (Registered Sanitarians). if'required. The Owner shall submit the name(s)of the consultant(s) perforating any monitoring on their behalf'to the local health department. (2) The applicant shall submit a site plan showing proposed sites for wastewater system. shall provide the longitude and latitude of the site,location of monitoring wells,and all drainage features that may influence the soil wetness conditions,and specify any proposed till and drainage modifications. (3) The applicant shall submit a monitoring plan indicating the proposed number,installation depth.screening depth.soil and well profile,materials and installation procedures for each monitoring well,and proposed method of analysis.A minimum of three water level monitoring wells shall be installed for water surface observation at each site. Additional wells shall be required for sites handling systems with a design flow greater than 600 gallons per day(minimum of one additional well per 600 gallons per day increment). (4) The local health department shall be given thc opportunity to conduct a site visit and verity the appropriateness of the proposed plan. Well locations shall include portions of the initial and replacement drainficld site(s)containing the most limiting soil'site conditions.Prior to installation of the wells the local health department shall approve the plan. If the plan is disapproved. the local health department shall include specific changes necessary for approval of thc monitoring plan. (5) Wells shall extend at least five feet below the natural soil surface,or existing soil surface for fill installed prior to July 1, 1977 meeting the requirements for consideration of a site with existing fill of G.S. 130A- 341 and the rules adopted pursuant thereto. However,a well or wells which extend(s)down only 40 inches may be used if they provide a continuous record of the water table for at least half of the monitoring period,and one or more shallower wells may be required on sites where shallow lateral water movement or perched soil wetness conditions arc anticipated. (6) Water surface in the monitoring wells shall be recorded at least daily from January 1 to April 30,taken at the same time during the day(plus or minus three hours).A rain(precipitation)gauge is required within one-half mile of the site. At least daily rainfall shall be recorded beginning no later than December I through April 30(the end of the well monitoring period). (7) interpretation Method for Direct Monitoring Procedure:The following method ofdeiennining depth to soil wetness condition from water surface observations in wells shall be used when the 60-day weighted rainfall index for the January through April monitoring period equals or exceeds the site's long-term (historic) 60-day weighted rainfall index for January to April rainfall with a 30 percent recurrence frequency(wetter than the 9th driest year of 30,on average). The 60-day weighted rainfall index for the monitoring period and historic rainfall record shall be computed as: WRI60 = 0.5Po+P, Pr +P*a+0.5PA Where\4'R1„t, = 60-day weighted rainfall index for January to April Pry = Total December rainfall Pt = Total January rainfall Pi = Total February rainfall Psi = Total March rainfall P., = Total April rainfall The Department shall prepare contour maps for each county where this interpretation procedure is proposed. Contours shall be prepared following standard interpolation procedures using normalized data collected from all National Weather Service Stations, or equivalent, from which appropriate data arc available,at least prior to February I of the monitoring season. Data from each station shall be normalized by fitting a 2-parameter gamma distribution to the 60-day weighted rainfall index computed for at least the most recent three decades of historic data, in accordance with procedures outlined in Chapter 18 of the National Engineering Handbook,NRCS,USDA.From this fitted distribution,the 60-day weighted rainfall index for January through April rainfall with a 30%,50°0, 70%and 80%recurrence frequency shall be computed for each Station,to provide the raw data points from which the contour maps shall be prepared. From these maps,the site's 60-day weighted rainfall index for the January through April monitoring period shall be compared to the long-term(historic)January to April 60-day weighted rainfall index at different expected recurrence frequencies. The soil wetness condition shall be determined as the highest level that is continuously saturated for the number of consecutive days during the January through April monitoring period shown in the following table: Recurrence Frequency Range Number of Consecutive Days January to April 60-Day of Continuous Saturation Weighted Rainfall Index for Soil Wetness Condition 30%to 49.9% 3 days or 72 hours 50%to 69.9% 6 days or 144 hours 70%to 79.9% 9 days or 216 hours 80%to I00aa 14 days or 336 hours (SI If monitoring well data is collected during monitoring periods that span multiple years.thc year which yields the highest(shallowest) soil wetness condition shall be applicable. (f) Monitoring and Modeling Procedure: A combination of monitoring and modeling may be used to determine a soil wetness condition utilizing the following monitoring procedures and interpretation method. (I) The procedures described for the Direct Monitoring Procedure in Subparagraphs(c)(I).(2),(3),(4),(5), and(6)of this Rule shall be used to monitor water surface elevation and precipitation for determining soil wetness conditions by a combination ofdircct observation and modeling.except that the rainfall gauge and each monitoring well shall use a recording device and a data file (DRAINMOD-compatible) shall be submitted with the report to the local health department(devices shall record rainfall at least hourly and well water level at least daily). (2) The ground water simulation model DRAINMOD shall be used to predict daily water levels over at least a 30 year historic time period after the model is calibrated using the water surface and rainfall observations made on-site during the monitoring period. The soil wetness condition shall be determined as thc highest level predicted by the model to be saturated for a 14-day continuous period between January 1 and April 30 with a recurrence frequency of30 percent(an average of at least 9 years in 30). (A) Weather input tiles, required to run the DRAINMOD,shall be developed from hourly rainfall gauge data taken within a half-mile of the site and from daily temperature and hourly or daily rainfall data collected over a minimum 30-year period from the closest available National Weather Service,or equivalent.measuring station to the site. DRAINMOD weather data files on file with the Department shall be made available upon request to the applicant or applicant's consultants. Daily maximum and minimum temperature data for the January 1 through April 30 monitoring period,plus for at least 30 days prior to this period.shall be obtained from the closest available weather station. (B) Soil and Site inputs for DRAINMOD. including a soils data file closest to the soil series identified,depths of soil horizons,estimated saturated hydraulic conductivity of each horizon. depth and spacing of drainage features and depression storage.shall be selected in accordance with procedures outlined in the DRAIN MOD Users Guide, and guidance is also available in Reports 333 and 342 of the University of North Carolinas Water Resources Research Institute. DRAINMOD soils data files on file with the Department shall be made available upon request to the applicant or applicant's consultants. (C) Inputs shall be based upon site specific soil profile descriptions Soil and site input factors shall be adjusted during the model calibration process to achieve a best fit by least squares analysis of the daily observations over the whole monitoring period (mean absolute deviation between measured and predicted values no greater than eight inches).and to achieve the best possible match between the highest water table depth during the monitoring period (measured-vs. predicted)that is saturated for 14 consecutive days. (D) For sites intended to receive over 1500 gallons per day, the soil wetness determination using DRAINMOD shall take into consideration the impact of wastewater application on the projected water table surface. (E) The ground water simulation analysis shall be prepared and submitted to the local health department by individuals qualified to use DRAINMOD by training and experience and who arc licensed or registered in North Carolina if required in G.S. S9C (Engineers). G.S. 89E (Geologists),and G.S.89F(Soil Scientists).The local health department or Owner may request a technical review by the Department prior to approval of the soil wetness condition determination. (g) Modeling Procedure: A soil wetness condition may be determined by application of DRAINMOD to predict daily water levels over at least a 30 year historic time period after all site-specific input pammcters have been obtained.as outlined in the DRAINMOD Users Guide. This modeling procedure shall be used when a ground water lowering system is proposed for a site with Group Ill or IV soils within 36 inches of the naturally occurring soil surface.This procedure shall also be used to evaluate sites with Group III or IV soils within 36 inches of the naturally occurring soil surface. where the soil wetness condition was initially determined using a procedure described in Paragraphs(e)or(f)of this Rule and where drainage modifications are proposed or when fill is proposed to be used in conjunction with existing or proposed drainage modifications.The soil wetness condition shall be determined as the highest level predicted by the model to be saturated fora 14-day continuous period between January 1 and April 30 with a recurrence frequency of 30 percent(an average oral least 9 years in 30). (1) Weather input files,required to run DRAINMOD,shall consist of hourly rainfall and daily temperature data collected over the entire period of record but for at least a 30-year period from the closest available National Weather Service,or equivalent,measuring station to the site.
